About Power Saving Mode

Your VAIO computer has power saving modes to conserve power while you are not using
the computer in addition to the normal operating mode.
Sleep mode
In Sleep mode, all unnecessary devices of your VAIO computer are turned off, though some
devices stay turned on to retain the computer's state including data you are working on.
Sleep mode is useful when you take a short rest, for example.
Hibernate mode
In Hibernate mode, the state of the current system is saved to the built-in storage device
and your VAIO computer is turned off. Hibernate mode is useful if you do not intend to use
the computer for a while.
About restart time and power consumption
The restart time from Sleep mode is the shortest, but your VAIO computer in Sleep mode
consumes power the most. When the computer is off, the time you take to start the computer
is longer than to resume it from power saving modes, but the computer can conserve power.
Note
By default, your VAIO computer automatically enters Hibernate mode when the battery
pack becomes weak. However, depending on the currently running software and
connected devices, Windows may not allow their tasks to be suspended, resulting in
failure to enter Hibernate mode. If this occurs and the battery pack is running out of
power, the computer will be turned off, resulting in loss of unsaved data.
While the computer is running on battery power, save data frequently and manually
place the computer into Hibernate mode, if necessary.
